ABSTRACT:
Circuits and methods to minimize total harmonic distortion in an integrated circuit feedback amplifier. Complementary transistors in the signal path are selected so that their base-to-collector capacitances are matched. Additionally, the DC operating currents of such transistors are matched, thereby cancelling non-linearities due to base-to-collector capacitances.
